SPECIFIGATI'ON forming part of Letters Patent N 0. 689,416, dated December 2 901- Application filed May 14, 1901- Serial No. 60,191. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS F. ROWLAND,

a citizen of the United States, residing in the borough of Manhattan, city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Anvil Mechanism, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same, in which similar reference characters refer to the same part throughout the several figures.

My invention relates to anvils used in connection with large forgings, and more particularly applicable to Welding and shaping large cylinders. The anvil is especially arranged to operate inside of such a cylinder in connection with any external cooperating shaping means.

Figure 1 is a side elevation of my anvil mechanism shown in connection with a suitable carriage supporting a cylinder, parts being shown in section. Fig. 2 is an end elevation of the same, partly in section, taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged sectional view of the anvil-cylinder and parts adjacent thereto.

D is aheavy supporting-column mounted upon a suitable foundation, and it carries the anvil-bar B, that is bolted to two brackets D D on the supporting-column. If desired, the anvil-bar may be mounted so as to be adjusted vertically by securing D D to D at the height desired, or it may move in any manner instead of being fixedly supported, and moving means may also be provided. The anvil-bar B is of preferably rectangular cross-section, as is shown in Fig. 2, and near the outer end of the same the anvil-support B is mounted so as to slide upon the anvilbar, the portion B which is cylindrical, projecting at right angles to the bar in a vertical position. The anvil-cylinder B fits about the cylindrical portion B of the support, so as to form a chamber A within the cylinder. The anvil-block A is rigidly attached to the anvil-cylinder and supports at its upper end the head A, which is connected to the block in any suitable way.

Within the anvil-support is formed a cylinder B the interior of which communicates with a passage B in the upper end of the support.

A is a valve-rod having a cut-off valve A thereon arranged to close the passage B when the anvil-cylinder has moved as far as is desired on the support, since this valve cuts ofi at that time any further communication between the cylindrical chamber B and the anvil-cylinder.

A is a nut locking the valve-rod A to the anvil-cylinder.

C is a pipe communicating with the chamber B and leading to a three-way-valve casing H, connected to the discharge-pipe C and to the supply-pipe C, the lever H being connected with the valve within the casing H.

The support-cylinder C is rigidly attached to the anvil-bar, and the piston C reciprocates within it. The piston-rod 0 secured to the piston O,is connected with the bracket B, attached to the anvil-support B. Suitable pipes 0 0 connect either end of the cylinder G with the valve-casing H 0 is a supply-pipe for this valve-casing, and C a discharge-pipe.

H is a suitable lever connected with the valve within the casingand arranged to either admit or discharge fluid from. either end of the cylinder.

Upon a suitable track E, I have shown two trucks E, mounted upon wheels E engaging the track. A pair of rolls E upon each truck are mounted in bearings E and support a large cylinder G, having a curved end G. By this means the cylinder can be moved along the track parallel to the anvil-bar and also can be revolved about its axis by moving the rolls E I have shown diagrammatically a gas-furnace F, supported upon a boom F within the cylinder G. This furnace will be of a construction Well known in this art and would operate inside the cylinder G to heat the same in connection with cooperating means outside the cylinder in a manner well known'in this art. i

The operation of my anvil is as follows: Suppose, for example, that it'was, desired to weld a circumferential seam between the cylinder G and the head G just above the anvil, as the same is shown in Fig. 1. The seam would first be heated, and to accomplish this the anvil-support and anvil carried thereby are moved away from the end of the anvilbar B by operating the support-cylinder 0 through its valve-lever H which would be moved so as to admit fluid under pressure-- that is to say, steam, compressed air, or any liquid under pressuresupplied through the pipe 0 to the pipe 0 and so to the outer end of the support-cylinder O, at the same time discharging the fluid from the inner end of the cylinder 0 through the pipe 0 and thedischarge-pipe 0 In this way the anvilsupport and anvil are moved inward along the anvil-bar away from the seam to be welded. The furnace F could then be thrust out to the seam and in connection with some other heating means outside the cylinder G, such as a gas-furnace, would heat the seam to a welding heat. The furnace would then be quickly withdrawn from the seam and the anvil-support and anvil thrust out toward the outer end of the anvil-bar by operating the valve-lever H so as to drive the piston O to the outer end of the cylinder 0, as is shown in Fig. 1. The anvil, of course, up to this time would be inits lowered position (shown in Fig. 2,) so as not to be in contact with the cylinder G. When the anvil is brought on its support directly under the seam to be welded, it would then be raised so as to support the seam by admitting fluid from the supply-pipe G to the pipe 0 by turning the valve-lever 11 in the proper direct-ion, so that fluid under pressure, either steam, air, or some other operating fluid, is admitted to the chamber B passes up through the passage 13, and enters the anvil-cylinder A thereby raising the anvil to any desired extent to support the seam to be welded. The welding could be done either by sledges in the hands of workmen or by any other means, cooperating with the anvil with in the cylinder G. The anvil-head A may have any desired contour, and in practice it is desirable to form a number of these heads, so that they can be varied as desired to suit the class of work to be performed. In pracnice I find in some cases that by simply lowering the anvil and without movingit inward along the bar'the furnace can be inserted against the seam. The movability of the anvil on the bar is, however, a very desirable feature for other purposes also. When this section of weld has been completed, the anvil may be lowered away from the seam by moving the valve-operating lever H so as to discharge the fluid within the anvil-cylinder through the passage 13, the chamber 15 and the pipe C and discharge pipe 0 The weight of the anvil and anvil-cylinder will cause the fluid to escape in this manner and the anvil will move downward of its own weight as far as desired. Some positive means of withdrawing the anvil could be provided, if desired. For instance, the anvil-cylinder could be arranged in connection with a doue'se Lie ble acting piston, or suitable withdrawing springs could assist the weight of the anvil and cylinder in moving the anvil toward the anvil-bar. If compressed air is used as the fluid actuating the anvil, the anvil will be supported against the work with a yielding pressure, since the anvil can yield slightly under any increase of pressure upon it. For someclasses of work this is a very desirable feature.

I have shown the cylindrical portion B of the anvil-support B as projecting at right angles to the anvil-bar B. This exact construction is not necessary, and for some classes of work it would be desirable to have the part 13 project at some other angle to the anvilbar, and it may also be desirable to have the anvil mounted so as to move not in a vertical direction, but in some other direction in some cases. s

I do not wish to be limited to the exact proportions and construction which I have shown in the drawings in this case. Many variations could be made therefrom by persons skilled in the art. The exact scope of my invention is set forth in the appended claims.
